The township’s police chief has again been put on administrative leave, the second time in four months.

A one-sentence letter from Administrator Marilyn Lyon dated Thursday states that Police Chief David Zink would remain on paid administrative leave until further notice.

No reason for the action was given in the letter. Trustee James Walters declined comment Thursday, citing personnel issues.

Neither Zink nor his attorney, Robert J. Tscholl, could not be reached for comment Thursday evening. Zink, who joined the Police Department in 1986 and became chief in March 2010, earns $91,271 a year.

In November, trustees put Zink, 49, on administrative leave after a female township officer accused him of sexual harassment. Trustees then suspended the chief for one month after an out-of-county investigator determined that Zink, who is married, had made multiple unwanted sexual advances during the past five years toward the female officer he supervises. The chief, who has repeatedly denied the accusations, returned to work Feb. 1.

Since at least early March, agents with the Ohio Bureau of Criminal Investigation have interviewed women who interacted with Zink, asking them questions about whether his actions toward them or other women had ever been inappropriate. It’s unclear whether the state’s investigation involves the same female officer who made the complaint against Zink in November.

Jill DeGreco, a spokeswoman for the Ohio Attorney General’s Office which serves as the legal arm for BCI, did not return a call seeking comment Thursday. BCI provides criminal investigative services to local, state, and federal law enforcement agencies upon request.
